I have no options for usb or mouse or keyboard in the Power Options. I just went to "Help and Support Center" and read this:
During Windows Setup, ACPI is installed only if all components present during Setup support power management. Some components, especially legacy components, do not support power management and can cause erratic behavior with Advanced Power Management (APM), or may prevent ACPI from being installed. Examples of such components are Industry Standard Architecture (ISA) components and an out-of-date BIOS
I've had my mouse and keyboard for forever ... can't seem to part; maybe that's the problem?
Anyway, thanks for your help!
